Abstract

Data processing apparatus having a slot (16) for receiving an additional optional board (18) includes both a high speed signal line and a low speed signal line connected to a slot circuit (7). A switching device (17, 19, 20, 21, 22) is provided for selectively switching between the high speed signal line and the low speed signal line for output.
